Electrical Distribution & Controls - Water Treatment

The stakes were high: get it wrong and sixty per cent of a large city’s water supply could dry up.  Careful planning and a thorough approach meant that a water treatment plant’s raw-water dosing system upgrade went without a hitch.

Pump Station - Hamilton City Council

The raw water pump station for Hamilton City's Water Treatment Plant was recently upgraded. This project required a new switchboard to replace the existing switchboard, complete with four 200kW motors all of which were VSD controlled. The upgrade was recently completed in a staged manner with minimal disruption to the process.

Switchgear Replacement - Fonterra

Time was of the essence when Ergo upgraded two 11kV substations and replaced four 400V switchboards at Fonterra’s Te Awamutu dairy factory.
